[CMake] Re: Making MEX file from CMAKE

[David Cole]

There are two options.

(1) Create a "*.def" file and add it as a source file to your target:
ADD_LIBRARY(... MODULE ... MyDefFile.def)

(2) In your source code, use __declspec(dllexport) to decorate the
function name... You can see examples of this in this VTK header file:
http://public.kitware.com/cgi-bin/viewcvs.cgi/Common/vtkWin32Header.h?rev=HEAD&view=auto

With the declspec approach in your source files, you need to be
careful to define it as dllexport when you're building your dll,
dllimport when a client is including your header file to link against
your dll and to use neither if you are building as a static library.

HTH,
David
